The bilingual girls who sang America the Beautiful in Coca-Cola's Super Bowl ad are explaining the meaning behind it.

"The message that we're sending through this video is so beautiful, that we are all the same," said Sushmitha, who sings in Hindi, in a YouTube video posted by Coca-Cola. "We just have different backgrounds and that's OK."

The ad features the patriotic song sung in Spanish, Tagalog, Mandarin, Hindi, Hebrew, Keres, Senegalese-French and Arabic.

"Everybody, they want to come into America to be free and make friends and just be happy," said Natalie, who sang in Hebrew, in another YouTube video posted by the company.

But the message to celebrate the country's diversity did not come across to all viewers. The ad, which aired in the first half of the Super Bowl on Sunday, spurred angry comments on Twitter and Facebook.

"Speak English or go home," said one commenter on the company's Facebook page. Another said, "Screwed up a beautiful song. No Coke for my family."

After the ad aired, the hashtag #SpeakAmerican started appearing on Twitter.

In an e-mail to USA TODAY, Coca-Cola said the ad "provides a snapshot of the real lives of Americans representing diverse ethnicities, religions, races and families, all found in the United States." USA TODAY Network has reached out to Coca-Cola requesting interviews with the girls.

Another of the singers, Kennedy, who sang in Senegalese-French, said the use of different languages was "awesome."
